Varolo is an advertising campaign that allows major corporations (like Coca Cola, Lysol, and others) to reach their target audiences with a high return on investment. Major corporations are desperately trying to find new ways to advertise to people as the newspaper continues to decline in demand and in an age of DVR. Varolo is the newest opportunity that actually pays you, the one being advertised to, to watch their advertisements. You can join the campaign and earn a little extra spending money by viewing and rating commercials and even trailers for major motion pictures. While the trick is to devote 5 to 10 minutes of each day rating what you see, you should also be motivated to invite others along through Facebook, Twitter and other social media so that you can increase what you profit each week.
One of the things I'm surprised your article doesn't mention is the tax advantages of this type of investment. The depreciation and rehab costs (purchasing distressed properties) can be huge deductions to ones income taxes, which none of the others have. Then, along with the appreciation of real estate, this passive income investment outperforms the notion of maxing out my 401k as well.
The obvious way to earn a second income is to get a part-time job. If you are not currently working, this is an excellent way to start as it gives you the freedom and flexibility to start other passive income opportunities.  The other option is to simply work from home full time which frees up commute time so you can focus on building more income streams.
Buy a small business: A local small business, like a car wash or a laundromat, is a great way to put money down on a money-making venture. Automate it so you don't have to be on the premises unless you're collecting money. Go into a local business with your eyes wide open - study the books, especially on income and expenses, and examine water and utility bills if your venture will be open 24 hours.

The use of the poverty line of $1 a day had long come under criticism for seeming arbitrary and using poor quality and limited data thus risking an underestimate of poverty. The $1.25 a day level is accompanied with some additional explanations and reasoning, including that it is a common level found amongst the poorest countries, and that $2.50 represents a typical poverty level amongst many more developing countries.
The key thing to note in those various streams is how few of them rely on my active participation on a daily basis and how they are fueled from savings. My active participation is in the blogs and $5 Meal Plan. Everything is passive, outside of routine maintenance like updating my net worth record, and none of them would be possible if I didn't have the savings to invest it.
When I purchase an existing online business, I look for cash flow over the past year and where the money comes from. I want the sources to be more passive so that it does not take a lot of my time. Also, typically I will make an offer that is 18 – 24 months of profit so that I know that I will get my money back within the next two years. I hope that helps!
If you happen to own a home, apartment, or office space, you have a great source for generating passive income at your fingertips. Peer-to-peer property rental site Airbnb has made it extremely easy for real estate owners to make extra money by renting out their homes to guests for short durations. If you're uncomfortable with such a model, you can also use sites like NestAway to find tenants for your property without having to deal with brokers.
Several donors are active in Ethiopia, with external aid of $3.7 billion in 2015. Both the government and the majority of international partners are keen to deepen the harmonization process in the spirit of the Paris Declaration (2005) and Accra Agenda for Action (2008). Ethiopia is a pilot country for the Organization for Economic Co-operation and Development Assistance Committee harmonization agenda, and for the European Union’s initiative on donor division of labor. Partners are currently considering how to build on this progress in light of the Accra Agenda.
While the credit rating of India was hit by its nuclear weapons tests in 1998, it has since been raised to investment level in 2003 by Standard & Poor's (S&P) and Moody's.[140] India experienced high growth rates, averaging 9% from 2003 to 2007.[141] Growth then moderated in 2008 due to the global financial crisis. In 2003, Goldman Sachs predicted that India's GDP in current prices would overtake France and Italy by 2020, Germany, UK and Russia by 2025 and Japan by 2035, making it the third-largest economy of the world, behind the US and China. India is often seen by most economists as a rising economic superpower which will play a major role in the 21st-century global economy.[142][143][needs update]
However, I think for those who are willing to do what it takes, the sky is the absolute limit. As an example, I’m trying to take a page out of FinancialSamauri’s book and create an online personal finance and investing blog. It is an enormous undertaking, and as a new blogger, there is a seemingly endless amount of work to be done. That said, I hope that one day I can not only generate some passive income from the hours of work I have put and will put into the project, but I hope to be able to help OTHERS reach their financial goals.
However, under certain circumstances, payment for personal services performed in the United States is not considered income from sources within the United States. For example, personal services performed by an independent nonresident alien contractor specifically exempted by a tax treaty. For more examples, see the Pay for Personal Service section in Publication 515, Withholding of Tax on Nonresident Aliens and Foreign Entities.

For a person working for a wage, their source of income is their job, or their labor (aka their time that they sell to someone). But you can own a house, and rent it out, and when your renters pay you renter every month, the source of that income check is your rental property, or your house. It would just be called rental income. If you have money in the bank in an account that pays interest, those interest payments are another source of income. We can say the source is interest payments, or we can identify the asset that is generating rent, and say your money in the bank that is generating “rent” (aka interest) is your source of income.
